Religious Belief
The rainbow has a place in legend owing to its beauty and the historical difficulty in explaining the phenomenon.
In Greek mythology, the rainbow was considered to be a path made by a messenger (Iris) between Earth and Heaven. In Chinese mythology, the rainbow was a slit in the sky sealed by goddess Nüwa using stones of five different colours.
In Hindu religion, the rainbow is called Indradhanush, meaning "the bow (Sanskrit and Hindi: dhanush is bow) of Indra, the god of lightning, thunder and rain". Another Indian mythology says the rainbow is the bow of Rama, the incarnation of Vishnu. It is called Ramdhonu in Bengali, dhonu (dhanush) meaning bow. Likewise, in mythology of Arabian Peninsula, the rainbow, called Qaus Quzaħ in Arabic, is the war bow of the god Quzaħ.
In Armenian mythology rainbow - is a belt of Tir, which was originally a god Sun, and then - god of knowledge. Eating options are apricot's belt, Belt of Our Lady or the Arch of God.
In Norse Mythology, a rainbow called the Bifröst Bridge connects the realms of Ásgard and Midgard, homes of the gods and humans, respectively. The Irish leprechaun's secret hiding place for his pot of gold is usually said to be at the end of the rainbow. This place is impossible to reach, because the rainbow is an optical effect which depends on the location of the viewer. When walking towards the end of a rainbow, it will appear to "move" further away (two people who simultaneously observe a rainbow at different locations will disagree about where a rainbow is).
Another ancient portrayal of the rainbow is given in the Epic of Gilgamesh: the rainbow is the "jewelled necklace of the Great Mother Ishtar" that she lifts into the sky as a promise that she "will never forget these days of the great flood" that destroyed her children. (The Epic of Gilgamesh, Tablet Eleven)
Then Ishtar arrived. She lifted up the necklace of great jewels that her father, Anu, had created to please her and said, "Heavenly gods, as surely as this jewelled necklace hangs upon my neck, I will never forget these days of the great flood. Let all of the gods except Enlil come to the offering. Enlil may not come, for without reason he brought forth the flood that destroyed my people."
According to Christian religion and Judaic religion, after Noah's flood the rainbow gained meaning as the sign of God's promise that terrestrial life would never again be destroyed by flood (Genesis 9:13–17):
I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh. And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth. And God said unto Noah, This is the token of the covenant, which I have established between me and all flesh that is upon the earth.
In the Dreamtime of Australian Aboriginal mythology, the rainbow snake is the deity governing water. In Amazonian cultures, rainbows have long been associated with malign spirits that cause harm, such as miscarriages and (especially) skin problems. In the Amuesha language of central Peru, certain diseases are called ayona’achartan, meaning "the rainbow hurt my skin". A tradition of closing one's mouth at the sight of a rainbow in order to avoid disease appears to pre-date the Incan empire.
In New Age and Hindu philosophy, the seven colours of the rainbow represent the seven chakras, from the first chakra (red) to the seventh chakra (violet).
Art
Rainbows are generally described as very colourful and peaceful. The rainbow occurs often in paintings. Frequently these have a symbolic or programmatic significance (for example, Albrecht Dürer's Melancholia I). In particular, the rainbow appears regularly in religious art (for example, Joseph Anton Koch's Noah's Thanksoffering). Romantic landscape painters such as Turner and Constable were more concerned with recording fleeting effects of light (for example, Constable's Salisbury Cathedral from the Meadows). Other notable examples appear in work by Hans Memling, Caspar David Friedrich, and Peter Paul Rubens.
Literature
The rainbow inspires metaphor and simile. Virginia Woolf in To the Lighthouse highlights the transience of life and Man's mortality through Mrs Ramsey's thought,
"it was all as ephemeral as a rainbow"
Wordsworth's 1802 poem "My Heart Leaps Up" begins:
My heart leaps up when I behold
A rainbow in the sky:
So was it when my life began;
So is it now I am a man;
So be it when I shall grow old,
Or let me die!...
The Newtonian deconstruction of the rainbow is said to have provoked John Keats to lament in his 1820 poem "Lamia":
Do not all charms fly
At the mere touch of cold philosophy?
There was an awful rainbow once in heaven:
We know her woof, her texture; she is given
In the dull catalogue of common things.
Philosophy will clip an Angel's wings,
Conquer all mysteries by rule and line,
Empty the haunted air, and gnomed mine –
Unweave a rainbow
In contrast to this is Richard Dawkins; talking about his book Unweaving the Rainbow: Science, Delusion and the Appetite for Wonder:
"My title is from Keats, who believed that Newton had destroyed all the poetry of the rainbow by reducing it to the prismatic colours. Keats could hardly have been more wrong, and my aim is to guide all who are tempted by a similar view, towards the opposite conclusion. Science is, or ought to be, the inspiration for great poetry."
Music
In "Rainbow Connection", a song known for being sung by Kermit the Frog, the idea of a rainbow is seen as something to wish on, as it is popularly seen as a vision, or symbol of hope.
In the "End of the Rainbow" by September, the singer sings about the rainbow, and how she will be at the end of the rainbow and her ex could see her there when he reaches the end of the rainbow.
End of the rainbow is an award winning stage play with music (or musical drama) by Peter Quilter.
The group Rainbow and the song "Rainbow Demon" by Uriah Heep.
"I Can Sing a Rainbow" is a popular children's classic song written by Arthur Hamilton, despite the name of the song, not all the colours mentioned are actually colours of the rainbow.
Ronnie James Dio used rainbows as a thematic element in many of his songs, particularly as singer and lyrics-writer for Ritchie Blackmore's band Rainbow. Most notable among these are the songs Catch the Rainbow, Rainbow Eyes and the Dio song Rainbow in the Dark.
The band Radiohead released an album in 2007 named, "In Rainbows."

Films
In A Shine of Rainbows, the young protagonist is promised to be taken into a rainbow.
In Marianne, a double rainbow was filmed by chance when Sandra is introduced for the first time.
In Rainbow, damage to a rainbow threatens the world at large.
In the film The Wizard of Oz, lead character Dorothy Gale sings the song "Over the Rainbow" where she fantasises about a place over the rainbow, where the world is in peace and harmony.
Flags
Rainbow flags tend to be used as a sign of a new era, of hope, or of social change. Rainbow flags have been used in many places over the centuries: in the German Peasants' War in the 16th century, as a symbol of the Cooperative movement; as a symbol of peace, especially in Italy; to represent the Tawantin Suyu, or Inca territory, mainly in Peru and Bolivia;[34] by some Druze communities in the Middle east; by the Jewish Autonomous Oblast; to represent the International Order of Rainbow for Girls since the early 1920s; and as a symbol of gay pride and LGBT social movements since the 1970s.
